Today, a report from TK Tech News elaborates further on the specs of the device, and it sounds like it will be a mid-range handset with a range-topping camera. The Lumia 830 is said to offer a 4.5-inch display – slightly smaller than the rumored Lumia 730's 4.7-inch screen – with a 720p HD resolution, as well as SD card support and some other "decent specs."

Significantly, the Lumia 830 is said to feature a 20-megapixel camera – likely the same unit used in Microsoft's other flagship Nokia Windows Phones, including the Lumia 930/Icon and Lumia 1520. That would put it in good company, given that the camera on those devices is among the best available on any handset today.

This would be an interesting approach, given that most mid-range handsets offer mediocre cameras. By cramming a top-notch camera into its mid-range Lumia 830, Microsoft might just carve out a niche for itself offering a better imaging experience on its more affordable devices.
